Patented Sept. 13, 1949 HOLDER FOR BELT FASTENERS Bernard Tebb, Hull, England, assignor to Mastabar Belt Fastener Company, Limited, Cleckheaton, England, a British company Application June 8, 1948, Serial No. 31,816 In Great Britain .iuly 17, 1947 2 Claims. 1

This invention relates to tools for use in applying fasteners to belts. Such fasteners are generally in the form of wire hooks of more or less U -shape with inturned ends, and they are caused to engage in the material of the belt by means of a clamping device which forces their sharpened inturned ends through the material of the belt. The loops of the wire fasteners then project from the ends of the belt, and are connected by a rod threaded through them.

In tools for effecting engagement of wire fasteners in this way it is well known to assemble the fasteners in the slots of a bar, to hold them in place by a pin passed through their loops, and to mount this bar between the jaws of a clamping device which serves to engage the wire fasteners with the belt. It is the object of the present invention to provide an improved form of slotted bar for holding the bent wire fasteners, the slotted bar being associated with a member acting as a captive pin for holding the fasteners in the slots of the bar, this pin being adapted to be withdrawn as far as is necessary for insertion and release of the fasteners, but not to become detached from the bar.

The invention is illustrated by way of example in the accompanying drawings, in which:

Figure 1 shows a perspective view of the slotted bar with the holding pin withdrawn;

Figure 2 is a longitudinal section of the bar a showing the holding pin inserted, and part of a set of wire hook fasteners secured thereby;

Figure 3 is a transverse section of the slotted bar with the pin engaging the hooks; and

Figure 4 is a plan View of one end of the bar shown in Figure 2.

The bar illustrated is of a type which may slide between side plates in the clamping tool so that it may be used to apply two or more groups of fasteners side by side to the end of a wide belt. The base a of the bar is the part which is mounted in and may slide in the hook closing tool, the two sides of the base being united by a saddle-shaped portion 1) which is transversely slotted over part of its length. Between the saddle-shaped portion b is inserted a metal filling piece 0, and at each side of the saddle-shaped portion 1) are applied plates at through which rivets e are passed to hold together the assembly of the saddle-shaped portion I) and the filling piece 0. The two sides of the base a. have another filling piece g between them, and are held together by rivets j passing transversely through the base and the filling piece g. Beneath the base in the example illustrated is another plate It, secured by rivets 1c ill) I 2; for example, extending into the base a, but this plate It is not an essential part of the slotted bar element.

The U-shaped pin p is mounted to slide in the saddle-shaped portion b of the bar, the upper or outer limb of the member 1) serving for holding the loops of the wire hook fasteners q in the slots of the saddle-shaped member I), as shown in Figures 2, 3 and 4. The lower or inner limb of the U-shaped pin projects between the filling pieces 0 and g, and has a turned-up end as shown at s in Figure 2. The loop of the pin p may have a chain 15 engaged with it, the other end of this chain being attached to a part of the tool so as to prevent the slotted bar as a Whole from being dissociated from the tool with which it is used,

The wire belt fasteners q are generally connected together in groups by a wire such as 0, Figure 2, welded to the backs of the hooks, and a group of these fastener elements has its loops passed into the slots of the saddle-shaped portion b of the bar, while the pin p is withdrawn as shown in Figure 2. The turned' up end s of the lower or inner limb of the pin p opposes some little resistance to its withdrawal by bearing against the rounded undersurface of the filling piece 0, but when the pin p is pulled with suficient force to cause the end 8 to slide under the filling piece c, the pin is easily withdrawn. The end s of the inner limb of the pin, however, forms a positive stop, preventing this pin from being withdrawn beyond the position in which the end s comes against the shoulder at w in the filling piece 0, but in this position the outer limb of the pin is clear of the slots in the saddle-shaped bar. When a set of wire fasteners is inserted, the pin is pushed in again, as in Figure 2, holding the wire fasteners in position, and the bar is adjusted in the closing appliance to the required position for inserting the fastener elements in this end of the belt. When the insertion is complete, the pin p is again withdrawn, and another set of wire hook fasteners is applied to the bar, ready for the next application of the fasteners to a belt end.

With the appliance as shown it will be understood that there is no possibility that the pin p shall become lost or unintentionally withdrawn when in use, and it holds the loops of the wire fasteners securely in position while their ends are being closed into the material of a belt by the jaws of the closing appliance.

I claim:

1. A device for holding wire hook fasteners for belts during their insertion, comprising a bar with a saddle-shaped portion, said saddle-shaped porsisting of inter-engageable stop surfaces formed on the said first limb and at one endofisaidslideway.

2. A device for holding wirezhookfasteners for belts during their insertion; comprising a channeled bar, said bar being formed with a plurality of transverse slots adapted toireceivethe loops of the wire hook fasteners, first and seoond=filling pieces fixed longitudinally within said channel,

a slideway formed between said first and-secondfilling pieces, a resilient U-shaped pin adapted slidably to embrace said first filling piece, said pin having one limb thereof adapted to retain said wire hooks in said slots and the second limb with the end thereof bent laterally of its longitudinally extending direction, and a projection formed on the end of the first filling piece nearest to the base of said: pin, said projection" extending across said slideway in the path ofthelaterallybent end of said second limb.
